Hematoxylin and Eosin staining: micrograph displays the proliferative and hypertrophic zones in control (a) and morphine-dependent (b) groups. Cell number comparison of proliferative and hypertrophic zones of the proximal (c-d) and distal (e-f) growth plate cartilage between morphine-dependent and control groups. Bars are representative of the SEM of samples. *P < 0.05, **P < 0.01, ***P < 0.001. n = 8
